SMC has redesigned the CQ2 compact cylinder with a new body, making it possible to mount auto switches on any of the 4 surfaces, depending on the installation conditions. Auto switch mounting grooves have replaced the CQ2s mounting rails, preventing projection of auto switches and improving ease and safety of work.
